Getting Started Front Panel SYSReset The IntelliFrameR mainframe provides you the ability to generate a backplane Activation SYSReset signal from the front panel. This feature allows you to reset the complete VXI system without having to power down the mainframe. A SYSReset activation is accomplished by pushing the right side (nonlighted side) of the On/Standby power switch.
Getting Started NOTE. To comply with VXIplug&play mounting specifications, position the rackmount adapter at the mounting holes with the adjacent identifier keys (see Figure 1–5). This results in 3.960 in (10.06 cm) from the module panel mounting surface to the rack frame mounting surface. VXIplug&play position key for VX1410A/11A/20A...
Getting Started Install the Mainframe Use the following procedure to install the VX1411A IntelliFrame Mainframe in in the Rack the rack: 1. Identify the right and left slide-out track assemblies: find the date code label on each assembly. The assembly to be mounted in the left side of the rack (the side nearest the left side of the mainframe when it is mounted in the rack) has a date code that ends with LH (for left hand).
Getting Started 6. Select the mounting position in the rack: select two 0.5-inch spaced holes in the front rail and verify that the 1.5-inch and 14.00-inch clearances exist relative to the mounting holes as shown in Figure 1–7. NOTE. The 14-inch vertical clearance is only valid for the mainframe without the rubber feet and cable trays.
Getting Started To mount with front and rear flanges inside of the rails, use mounting method B shown in Figure 1–8 when doing step 8. This mounting method assumes untapped holes. 8. Using the mounting method determined from the previous step, secure the right slide-out track assembly to the front and rear rails.
Getting Started 12. Lift the mainframe and insert the left and right tracks that extend from the rear of the mainframe into the ends of the tracks that you just extended. Make sure that the tracks mounted on the mainframe slip just inside the inner tracks that you extended earlier.
Getting Started Install the Option 2R Refer to Figure 1–10 and perform the following steps to install the rackmount Rackmount Door door for Option 2R: 1. Install the bottom halves of the two hinges to the left rackmount bracket as shown in Figure 1–10.
Page 39
Getting Started Configuration After installing the mainframe, you are ready to configure it for your applica- tions. If you have not already done so, install your VXIbus modules in the mainframe following the installation guidelines for your VXIbus module. Module Selection and The VX1411A IntelliFrame Mainframe is UL listed to UL 3111-1 and CAN/ Design Guidelines CSA C22.2 No.
Install either the optional single-wide or double-wide fillers. CAUTION. To avoid damage caused by heat use only Tektronix front panels; otherwise the shutters may activate, effectively robbing airflow from installed modules. Installing the fillers provides improved cooling for installed modules and improved EMI shielding.
Getting Started Safety and Chassis The left rear of the VX1411A IntelliFrame Mainframe has a connection point for Grounds the chassis ground (see Figure 1–12). WARNING. To avoid personal injury the safety ground screw must always be in place to ensure the proper bonding of the power supply to the mainframe. You can use the chassis ground connection to connect the grounds of one or more instruments to the mainframe.
Getting Started EMI Configurations Perform the following steps if you intend to install the optional EMI Intermodule shields and/or EMI filler panels. (Part numbers are listed under Optional Accessories on page 5–8): NOTE. It is only necessary to install the EMI intermodule shields if your VXIbus module does not have EMI shielding.
Getting Started Functional Check and Performance Verification Use the information in this section to determine that the VX1411A IntelliFrame Mainframe operates properly. The functional check and performance verification consist of checking the power supply voltages. To check these voltages you will need an extender card and a digital voltmeter.
Operating Basics This chapter provides a brief overview of the VX1411A IntelliFrame Mainframe including illustrations and descriptions of switches, indicators, and connectors. Figure 2–1 shows the front view of the VX1411A IntelliFrame Mainframe. All of the mainframe slots are labeled on the top and bottom of the mainframe. Slot 0 is reserved for the mainframe controller;...
Operating Basics The On/Standby switch on the top-left corner of the front panel applies DC voltages to the mainframe. The switch is a momentary contact switch. The switch is lighted when DC voltages are applied to the mainframe. This switch can also generate a SysReset on the VXI Backplane, refer to Appendix B: Special Configuration for configuration information.
Page 48
Operating Basics Fan Speed Control The Fan Speed switch controls the speed of the system cooling fans. When the switch is set to the variable position, the fans are set to a variable speed to reduce fan noise. The fans are automatically adjusted by the mainframe to minimize fan noise and provide appropriate cooling.
